If angle a is congruent to itself by the reflexive property, which transformation could be used to prove triangle abc is similar to triangle ade by aa similarity postulate?

a. translate triangle ade so that point d lies on point b to confirm angle d is congruent to angle b.

b. translate triangle ade so that point b lies on point e to confirm angle b is congruent to angle e.

c. dilate triangle abc from point a by the ratio segment ad over segment ab to confirm segment ad is similar to segment ab

d. dilate triangle abc from point a by the ratio segment ae over ac to confirm segment ae is similar to segment ac.

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
